Hello, Alpine Linux has just released a Xen Dom0 LiveCD that contains a Linux Kernel 3.3.6 with PaX and grsec patches and Xen 4.1.2 with the CVE fixes. This LiveCD doesn''t include any kind of X11 desktop, as it is intended for server use only. The LiveCD is part of the Alpine Linux distribution, and will be updated every time there is an Alpine Linux release, ensuring that the users always get the latest versions of the software. For those of you that don''t know what Alpine Linux has to offer, here''s a little extract from the Alpine Linux webpage: Alpine Linux was designed with security in mind. It has proactive security features, such as PaX and SSP, that prevent security holes from being exploited. Alpine Linux uses the uClibc C library and all of the base tools from BusyBox. These are normally found on embedded systems and are smaller than the tools found on GNU/Linux systems. The traditional GNU/Linux base system is over 100MB in size (excluding the kernel), while the base system in Alpine Linux is only 4-5MB in size (excluding the kernel). It''s great for experimenting: Since the system configuration can be backed up to a single file, you will be able to test configurations before deploying them to production systems. (You can find much more information on the Alpine Linux web page: http://alpinelinux.org/about) Also, Alpine Linux has the option to run from RAM, even when installed to a HDD or USB, allowing the user to save it''s changes on a USB, floppy or other medium which then gets read at boot to leave the system as it was before the reboot. This is specially interesting for Xen Dom0, since it allows to have the whole system on RAM, which is immune to HDD crashes (you could have access to your Dom0 even after and HDD crash) and doesn''t consume I/O resources. This is still the first and experimental release of this LiveCD, so I would like to encourage Xen users to test it, and report back with the results. The LiveCD can be found at: http://alpinelinux.org/downloads Regards, Roger.

I''m missing however a bootable USB image. We are already in 21st century and many new systems simply don''t have CD/DVD drives anymore. Most of my servers run without it as I use *only* USB sticks as boot / install media instead of slow CD/DVD based images.

I ask because this could be an excellent solution to one of my current requirements.

I''d personally found it a great distribution for building a firewall, although it''s more than a bit behind in its package of shorewall. Fortunately it''s not hard to add that to an Alpine Linux installation, although you lose the spiffy web interface to it due to version skew. > Also, Alpine Linux has the option to run from RAM, even > when installed to a HDD or USB, allowing the user to > save it''s changes on a USB, floppy or other medium which > then gets read at boot to leave the system as it was > before the reboot.

Most of my servers run without it as I use *only* USB sticks as boot / install media instead of slow CD/DVD based images. Use these instructions to create a base USB install and run from there: http://wiki.alpinelinux.org/wiki/Installing_Alpine_on_USB Here''s how to backup the particulars of a USB stick: http://wiki.alpinelinux.org/wiki/Back_Up_a_Flash_Memory_Installation In general the wiki is an excellent place to find your answers to these sorts of questions. - Harold

The point is however a downloadable image for USB sticks. Otherwise thousend of people will waste their time to convert the existing iso image, even they simply want only to test the image within let say 15 minutes. At least my time resources are very limited. I am wondering every time about managers or deveolpers (even in big companies) who still didn''t get it. regards, Mark -- ms@it-infrastrukturen.org http://rsync.it-infrastrukturen.org

Alpine Linux is great for lightweight systems. :) I am in the final stages of preparing a Ubuntu Linux based Dom0 LiveCD/USB. I should have it ready sometime this week hopefully, $dayjob has been getting in the way.
